used in the Directive Issuance System are instructions,notices, and change transmittals.Instructions are directives that contain informationof a continuing nature or require continuing action. Aninstruction has a continuing reference value, and iseffective until the originator cancels or supersedes it.Notices are directives of a onetime nature or thatcontain information or require action applicable for abrief period only. A notice has the same force and effectas an instruction, but it does not have permanent value.Therefore, it contains provisions for its owncancellation. When the exact length of time a notice isto remain in effect cannot be determined at the time ofissuance, the specific date for record purposes is set farenough in the future to allow all necessary use of thenotice.A change transmittal is the medium used to transmitchanges to an instruction or, under extenuatingcircumstances, a notice. Each transmittal describes thenature of the change and gives directions for makingthem. Directives are identified by designationinformation. Using SECNAVINST 5215.1 as anexample, SECNAV is the issuing authority, INST isthe type of directive, 5215 is the subject identificationnumber, 1 is the consecutive numbering forinstructions by the directive control point. Theconsecutive numbers assigned to instructions, which arelater canceled, are not reused. The period (.) is used toseparate the subject identification and consecutivenumbering. When a change is made, the changetransmittal number and its date are shown on the page(s)that contain(s) the change; for example,SECNAVINST 5215.1, Change Transmittal 1, 26 Jan1993. A revised instruction will retain all thedesignation information with the addition of a suffixcapital letter (the first revision A, the second B, etc.)immediately following the consecutive number. Eachchange transmittal is identified in the designation lineof the transmittal by the same number as the directive itchanges (in the case of notices, the date), plus anassigned change transmittal number added to theidentification; for example, SECNAVINST 5215.2,Change Transmittal 1.You will use different instructions and notices whenperforming your daily tasks. They are issued by variouscommands, bureaus, ships, stations, and operatingforces. Many of the directives used in aircraftmaintenance are issued by Headquarters, Naval AirSystems Command. They are known as NAVAIRinstructions or notices. The directives issued by Chiefof Naval Operations are known as OPNAV instructionsor notices. Refer to Department of the Navy DirectivesIssuance System, SECNAVINST 5215.1, for moreinformation.The NAMP, OPNAVINST 4790.2 (series), issponsored and directed by the Chief of NavalOperations (CNO). It addresses CNO concepts,objectives, policies, programs, organizations, andresponsibilities as they apply to aviation maintenancefor each level of command. This instruction outlines theduties and responsibilities of a supervisor working in thematerial control division of a squadron or AIMD, or inthe aviation support division of the supply department.The Uniform Material Movement and IssuePriority System (UMMIPS), OPNAVINST 4614.1F,contains the following information:lllllllForce activity designator (F/AD)Issue policy designatorRequisition processingDelivery datingMission essential materialAbuses and policing of the priority systemExpedited handling of critically needed itemsThe Shore and Fleet Small Purchase and OtherSimplified Purchase Procedures, NAVSUPINST4200.85 (series), provides instruction and guidanceconcerning purchase or procurement of material fromcommercial suppliers.

It contains illustrations andexplanations that make it a valuable training aid as wellas a handy reference.You will often be required to prepare or processrequisitions for component parts required forincorporation of technical directives (TDs). A TD maydirect that component parts or material be added,removed, changed, altered, relocated, or repositioned.NAVAIR has management responsibility for theConfiguration Management Program. NAVAIRINST5218.8 contains specific information concerning the TDprogram.
